BOAT.

Specification of Letters Patent.

Patented Aug. 28. 1906.

Application filed August 16, 1905. Serial No. 274,436.

To all IUD/07H 'fr' 71mg concern:

Be it known that I, TIMOTHY HANLEY, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,haveinvented new and useful Improvements in Boats, of which thefollowing is a specification.

The invention relates to an improvemen in manually-propelled boats,comprehending, specifically, the mechanism adapted for manual operationto propel the boat through the water.

The main object of the present invention is the production of meanssupported within the boat and arranged to be manually operated by one ormore persons to impart a desired revolution to the propeller.

Another object of the invention is to so construct and arrange theoperating mechanism that the operator may simultaneously or alternatelyinfluence said mechanism.

The preferred details of structure of the invention will be described inthe following specification, reference being had particularly to theaccompanying drawings, in

- which Figure 1 is a longitudinal central section through a boat fittedwith my improved mechanism, the operating parts being shown inelevation, Fig. 2 is atop plan view of the same. Fig. 3 is a verticalsection through the operating mechanism, the power-shaft being shown inelevation. Fig. 4 is a transverse section taken above one of the drumsof the operating mechanism. Fig. 5 is a perspective view illustrating aportion of the foot-rest of the steering-gear.

Referring to the drawings, my improved mechanism is arranged to besecured within a boat 1, which issuitably provided with transverse seats2, arranged on opposite sides of the mechanism and positioned topermitconvenient operation thereof, as hereinafter described.

The operating mechanism comprises abase 3, having four equally-spacedradially-projecting lugs 1, and preferablyprovidedwith struts orbrace-bars 5, projecting from the base and adapted to be suitablysecured to the sides or other permanent part of the boat. A head-block6, similar in dimensions to the base 3 and provided with similar lugs 7,is supported above the base through the me dium of uprights 8, joininthe verticallyalined ears of the base an head-block. A power-shaft 9 issupported centrally of the base and head-block, being revolubly mountedin each and preferably pointed at the lower end and supported in abearing-block 10, fixed to the keelson or base timbers of the boat. Themotive power for the shaft is arranged in duplicate, each set comprisinga drum 11 and a spring 12, and as these parts are in duplicate in eachset a detailed description of one will suffice for both. The drum 11comprises a concentric ring 13, loosely encircling the power-shaft, theinner periphery of the ring being formed to provide a series of toothedshaped notches 14, hereinafter termed the ratchet of the drum. The shaft9 is provided in horizontal alinement with the ring 13 with a recess 15,in which is seated a spring-pressed dog 16, having an inclined end face,whereby to permit operative engagement between the ratchet-teeth and dogin the revolution of the ratchet in one direction and the independentrevolution of the parts in the movement of the ratchet in the reversedirection. The ring 13 is pro vided with a depending sleeve 17preferably of less diameter than the ring and also encircling thepower-shaft. The coil-spring 12 is secured at one end to one of theuprights 8 and at the opposite end to the sleeve 17, being coiled aboutthe sleeve, so that the operative force of said spring when undertension will revolve the sleeve, and thereby the drum, in a direction topermit the ratchet to override the dog without engagement therewiththatis, in a direction reverse to its movement when imparting motion to thepower-shaft.

It will be noted that the respective sets of motive power are arrangedone above the other on the power-shaft, and they will be respectivelyhereinafter referred to as the up per and lower driving mechanism. Thedrums of the respective driving mechanisms are provided-with anoperating means, such as a strap 18, to terminally secure to and coiledabout the drum-ring 13. The strap of the upper driving mechanismprojects from its drum in a reverse direction to the strap of the lowermechanism, said straps being reversely coiled. about the respectivedrums, so that a pull upon either or both of the straps will operate theshaft. The free ends of each of the straps project throughbearing-blocks 19, mounted on a convenient upright 8, and are terminallyprovided with hand-grips 20 for ease of operation. It will be noted thatthe respective straps are coiled reversely to ITO the particularoperating-spring, whereby the uncoiling of the strap will put the springunder tension, with the effect to recoil the strap upon release of thepull thereon. Near the lower end a gear 2]. is keyed to the powershaftand arranged to intermesh with a pinion 22, supported on the inner end.of a screwshaft 23, which shaft extends rearwardly through the usualbearing 24 and is provided beyond the hull of the boat with the usualscrew or other propeller 25.

The steering apparatus particularly adapted for use in connection withmy power mechanism comprises a collar 26, loosely encircling thepower-shaft and supported upon the gear 21. The collar is provided withdiametrically opposite projecting arms 27, having foot-rests 28 at theirouter ends, each foot-rest being preferably provided with acentrally-arranged vertically-proj ecting heelplate 29, whereby thesteering mechanism may be operated by either or both of the occupants.The rudder 30 is pivotally mounted in the usual manner in rear of thepropeller, the terminals of the cross-head 31 thereof being connectedthrough the medium of flexible connections 32 with the respective arms27, as clearly shown in Fig. 2. Suitable guide-rings 33 are provided toreceive and guide said connections 32.

In operation the occupants of the seat 2 by grasping the handholds 20 ofthe strap and exerting a pull thereon will impart revolution to thedrum-ratchet 13, and thereby to the power-shaft. The movement of thepowershaft is transmitted to the propeller, through the operativeengagement of the gear 21 and 22, as will be obvious. Upon release ofthe pull upon the strap, the springs 12, which have been put undertension in the uncoiling of the strap, will operate to recoil the strapabout the drum ready for the next operation, this resetting movementturning the drumratchet in the reverse direction, which move. ment is ofcourse independent of the movement of the shaft, owing to the describedarrangement of the ratchet and dog. During the forward movement of theboat the occupant of either seat by placing his feet upon the rests 28,preferably with his heel against the plate 29, may effectively controlthe direction of the boat through obvious operation of the steeringmechanism. As the upper and lower driving mechanisms are arranged foroperation through independent connection with the powershaft, it isobvious that the boat may be propelled by the operation of one or bothstraps, and that in the latter event the respective straps may besimultaneously or alternately operated, as may be desired.

The mechanism described provides for the ready and convenient propulsionof the boat by the operation of one or more persons without regard as towhether they are working in unison or not.

Having thus described the invention, what is claimed as new is 1. Thecombination with a boat having a propeller-shaft, of a power-shaftgeared thereto, duplicate driving mechanism arranged for cooperationwith the power-shaft, and manuallyoperated means connected with each ofsaid driving mechanisms, said operating means extending in oppositedirections from the driving mechanisms to permit operation of thepropeller-shaft from either or both ends of the boat, andrudderoperating means revolubly supported by the power-shaft.

2. The combination with a boat having a propeller-shaft, of apower-shaft geared thereto, duplicate driving mechanism arranged forconnection with said shaft, each of said mechanisms comprising a drum, apawland-ratchet mechanism between the drum and power-shaft, automaticmeans for operating the drum in one direction, and a strap connectedwith the drum, the respective straps extending in reverse directionsfrom the driving mechanisms, arms operatively supported by thepower-shaft and connected. to the steering mechanism, each of said armshaving a foot-rest provided with a centrallyprojecting heel-plate,whereby said arms may be operated from either side of the drivingmechanism.

3. The combination with a boat having a propeller-shaft provided with agear-pinion, of a power-shaft having a gear fixed thereto and adapted tointerinesh with the pinion, and a driving mechanism arranged forconnection with said shaft, said mechanism comprising a drum, apawl-and-ratchet connection. between the drum and power-shaft, a springterminally secured to the drum and coiled about the same, a-strap coiledabout the drum in a direction reverse to the coil of the spring and armshaving operative connection with the steering-gear, said arms beingrevolubly mounted on the power-shaft and supported by the gear thereon.

In testimony whereof I aflix my signature in presence of two witnesses.
